The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

In the present disclosure, the terms "comprises" and "comprising," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a system, article, or apparatus that comprises a list of elements is not necessarily limited to those elements expressly listed but may include other elements not expressly listed or inherent to such article or apparatus.

Referring to fig. 1 to 4, an embodiment of the present utility model provides a cosmetic packing tube 10 including a central bundle core 100 for accommodating cosmetics and a base 200 fixedly connected with the central bundle core 100.

Along the axial direction of the packaging tube, the middle binding core 100 has a top side and a bottom side opposite to each other, wherein the prior art can be adopted, for example, the middle binding core 100 comprises a bead, a fork, a screw and a middle binding, the bead is a container for containing paste, the fork is in rotating fit with the screw, a guide groove is formed in the fork, the bead is arranged in the fork and can slide along the guide groove, at least one part of the bead also extends out of the fork and is matched with the screw, the bead is driven to slide along the guide groove to push out or hide the paste in the fork when the screw rotates, the middle binding is fixed with the screw, the protection and decoration effects are achieved, and the middle binding and the screw can be integrated into a whole.

The existing middle beam core 100 is generally fixed by adopting a buckling position when being connected with the base 200, and the buckling position is generally manufactured by adopting a mode that a mold core is forced to be taken off or is drawn in through the mold core, but the manufactured buckling position has the problem of easy separation or easy deformation during assembly due to the limitation of a mold structure.

To solve this problem, the base 200 of the present utility model includes an outer bottom tube 210 made of a metal material and an inner bottom tube 220 made of a plastic material, and an inner wall of the inner bottom tube 220 has a coupling portion connecting the middle core 100 and is formed by surrounding left and right lobes.

When the buckling position (the combining part) is formed on the inner bottom pipe 220 formed by surrounding the left and right halves, the inner bottom pipe is not required to be strongly separated from the die, so that deeper buckling positions can be formed, even the end parts of the buckling positions can be made into right angles, the requirement of difficult separation is met, and the problem that products are deformed when the inner bottom pipe is assembled and pressed in is avoided.

Referring to fig. 3-4, there is a connecting structure 240 between the left and right lobes that limits separation of the two. Specifically, the connection structure 240 includes a connection piece 222 disposed on the left lobe 221 and overlapping the right lobe 225, and a bump 226 fastened to the connection piece 222. The connecting piece 222 is provided with a connecting port 223, and the protruding point 226 is matched with the connecting port 223 to realize the buckling connection with the connecting piece 222. Of course, the left lobe 221 and the right lobe 225 are relatively speaking, so the connecting piece 222 may be disposed on the right lobe 225, and the bump 226 may be disposed on the left lobe 221 correspondingly.

Along the packing tube axial direction, connection structure 240 specifically sets up in the laminating face 230 department that two lamellas enclose, in order to make both be convenient for the lock, and bump 226 has guide slope 227 towards one side of connection piece 222, when needs lock, only need apply the opposite force with two lamellas, when connection piece 222 and bump 226 contact, connection piece 222 can follow guide slope 227 motion until with bump 226 complete lock. Of course, considering the problem of uniform stress when the left flap 221 and the right flap 225 are surrounded, the number of the connecting pieces 222 and the protruding points 226 may be plural, and in this embodiment, the number is 2 respectively, and the connecting pieces and the protruding points are distributed on two sides of the inner bottom tube 220 in the axial direction.

The bottom of the inner bottom tube 220 is closed with a flexible connecting band 250 therebetween. The connecting band 250 connects the left and right flaps so that the two flaps are paired, thereby avoiding the loss of one of the flaps and improving the assembly efficiency. Of course, the problems of reducing the number of parts and improving the production efficiency are considered, and the left and right flaps are integrally injection molded.

In one embodiment, the joint includes a snap ring 231 that limits axial movement of the central core 100 and an axial rib 232 that limits relative rotation of the central core 100. Specifically, the number of the axial ribs 232 is a plurality of and evenly distributed, the snap ring 231 is disposed above the axial ribs 232, and the middle beam core 100 is provided with a clamping groove 110 matched with the snap ring 231 and a groove 120 matched with the axial ribs 232.

When the middle binding core 100 is specifically assembled with the inner bottom pipe 220, the left and right halves can be partially surrounded (the connecting sheet 222 and the convex point 226 are not buckled), then the middle binding core 100 is inserted into the inner bottom pipe 220, so that the clamping groove 110 is aligned with the clamping ring 231, the groove 120 and the axial convex rib 232 to be matched, at the moment, the left and right halves are completely surrounded (the connecting sheet 222 and the convex point 226 are buckled), and the fixation of the middle binding core 100 and the inner bottom pipe 220 can be realized, and the risk of product deformation is avoided.

In order to increase the weight of the cosmetic packing tube 10 to enhance the texture, the outer bottom tube 210 is provided inside with a weight member 260. Specifically, the weighting member 260 is clamped to the bottom of the inner bottom tube 220.

In one embodiment, the top of the outsole tube 210 is thinned and then folded back to form a double-layered structure.

In order to achieve the fixation between the outer bottom tube 210 and the inner bottom tube 220, the outer circumference of the inner bottom tube 220 is provided with a plurality of uniformly arranged positioning ribs 228, and the inner bottom tube 220 is in interference fit with the inner wall of the outer bottom tube 210 through the positioning ribs 228.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description. When technical features of different embodiments are embodied in the same drawing, the drawing can be regarded as a combination of the embodiments concerned also being disclosed at the same time.

The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the claims. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model.
